The Distribution of Power in the U.S. Supreme Court
ResearchPublished 1981
ResearchPublished 1981
The distribution of power among the nine justices of the U.S. Supreme Court is calculated using techniques of factor analysis in conjunction with a generalized Shapley-Shubik power index that takes into account the ideological or philosophical profiles of the voters. A three-dimensional profile space is constructed, based on data from the 1977-78 term. It is found that, because of his central position in this space, Justice Powell has the highest probability — about 35 percent — of being pivotal in a typical decision.
